针对你遇到的 libbpf: load bpf program failed: permission denied 问题,这里有一些可能的解决步骤和考虑因素。按照你的提示,我将分点详细解释: 确认用户具有加载BPF程序的必要权限: BPF(Berkeley Packet Filter)程序通常需要特定的权限来访问内核资源。如果你不是以root用户身份运行程序,可能会遇到权限问题。 尝试以...
I'm using a application that is using bcc, the BPFCollector. I'm trying to run a InfluxDB server and I keep receiving this error coming from bcc package: Traceback (most recent call last): File "InDBClient.py", line 49, in collector = In...

create a skeleton header file, and load with libbpf. The BPF is always compiled from source so less chance that source and instructions diverge. Also resolves issue where libbpf and source get out of sync. The program is only loaded once, so if multiple rules are created ...
Those BPF errors are normal as the user namespace prevents loading of eBPF program for security reasons. Systemd handles that properly and turns it into a non-fatal warning. In LXD we have the beginning of system call interception for eBPF which may make this kind of thing work in the futu...
However, when I try to run xdp-filter, I get this: ./xdp-filter load eth11 Couldn't load BPF program: Unknown error 4001 I'll note that before I ran that, I did remove any running xdp programs (ip link set dev eth11 xdp off)Member...
